There's just one weekend left in the 2015 regular season, but what should you be keeping an eye on as the year draws to a close and the playoffs get set to begin?

On this week's edition of The Strike Zone podcast, SI.com baseball writer Cliff Corcoran joins host Ted Keith to talk about the race for the postseason, including whether the Astros can stop their late-season slide and hold onto a wild-card spot, as well as which division winners should be World Series favorites and which could be disappointments. Cliff and Ted also discuss which teams that missed the playoffs this year could be contenders in 2016, focusing on the Diamondbacks and Red Sox, before turning their attention to the Nationals and what moves they need to make to turn things around for next season.
